Arc spraying the principle and characteristics of the mold

Arc spraying molding technology is the two molds dedicated live wire feeding continuously through the catheter, the wire intersects the front of the gun to form an arc, the wire is melted by the electric arc, under the action of compressed air, the molten metal Atomized into metal particles and sprayed to the surface of the mold at a certain speed, superposed one on top of the other, and deposited to form a metal sprayed layer with high density and high bonding strength, that is, the shell (or body) of the mold cavity, The shape of the inner wall of the shell completely matches the surface of the sample mold to form the desired mold cavity. Metal shell formed by spraying and other matrix material filled with reinforcement, combined into one, together with other components, that is, to form a complete set of mold. This molding method is similar to electroforming, but not exactly alike. It mold making process is simple, easy to grasp, mold making cycle is short, the cost is low. Compared with the production of the same shape and size of the steel mold, mold cycle and mold costs can be reduced by more than 60%.
